Colour difference with text illustrations - print brochure

[Josephine36660218rb1p]

Hi everyone, 

I'm trying to crack the code but it's just not working. 

Sometimes when you are working in indesign, the colors look faded, but when you save them, they come back to life. Great! 

This is happening for me for most of it, just not my text. 

I have a few illustrations in a specific colour (#0000ff) but I also want to use this colour for titles and text in general. But this has still faded. (even when I export it as print or interactive.) It's hard to explain, and that's why I'm not finding any solutions. I've attached a few screenshots with all of my setting. 

Please help me, it's driving me crazy and I really need this.

Thank you for your help if anyone can actually understand my explanations.

3. Front page - illustrations with transparency blend settings on RGB

4.  Front page - illustrations with transparency blend settings on CMYK

5. Exported pages - print - spread - the left blue is the correct blue but the titles on the right is the faded blue and that is my problem.

Your color is outside the gamut of the colors you can physically print. That bright of a Blue cannot be reproduced out of CMYK inks, so what you get is the best possible representation based on your colour settings. Right now, yours is set to reproduce CMYK in the colours possible on a Coated Web Press. This is a usual default and is pretty good for general purpose, but you could be more specific and change this to a more modern setting (e.g. GRACOL or FOGRA), but you WILL still see a substantial change in color. You can proof this within your document by selecting View > Proof Colors. If you toggle this on and off, you will see how your colors will change in print based on the View > Proof Setup, which should be your selected CMYK profile.

Document Blend space is used to determine how objects interact, especially of different color spaces.

As per Brad @ Roaring Mouse you're using Hexadecimal colours for print - outside of CMYK gamuts.
